WILLIAM E. CLOU'GII, OF REDONDO BEACH, CAI'JIIEORNIA.l

To all 'whom t may concern:

Be it known that I, WILLIAM E. CLoUeH, a citizen of the United States, residing at Redondo Beach, in the county of Los Angeles and State of California, have invented a new and .useful Hand and Foot Accelerator for Carbureters of Automobile Engines.

VThis invention relates to accelerator operating means and itmay be said to consist of new and useful features and in improved construction, combination and arrangement of parts and will' be described as embodied in the preferred form of apparatus herein shown.

The invention comprises an accelerator operating means that can be actuated by both the hand and foot or by either in lone direction to open the throttle valve; land au-y tomatic means are provided for vmoving the mechanism in the opposite direction to close the valve. n. .j

Another feature of the invention is lshown I in the means for adjusting the parts to fully open or closethe throttle valve. I

Objects of the invention are simplicity of construction,

and ease of installation on automobilesalready in operation. .Y

` this invention a foot lever v tically all'driviiig'conditions; and this isef- :fected by a slight change of present coni, structions.

In carrying out is. connected to the usual throttle lever in common use so that eitherv pressure of the foot orv pressure of the'hand may be used to affiliate the engine.

A n radvantage of this invention ,is that control of the engine is insured under prac- Other objects, advantages and features of the invention may appear from the accom' panying drawings, the subjoined detailed 'description' and the appended claims. f- The drawings illustrateuthe invention.

with the parts shown yfull size.

In' detail the engine 1, steering post 2 and foot board 3 shown by dotted lines in Fig. 1 are old and well understood; and a detailed description of them is not' given; also the carbureter 4 'that is attachedy to the engine manifold 5 ca-n be of any type.'

As is well kno-wn the throttle valve 6'of the carbureter isprovided with a throttle lever-7 which lever hashe'retofore been connected by a rod to a linger 8 thatA is secured to the'bottom end of a rod 9 thaty is attached to the steering post 2 of the automobile and which has on the upperend thereof the hand lever 10, by which means the throttle valve has been opened and closed. A y

' In applying this invention the usual rod `connecting thethrottle lever 7 with the finbolt 14, which bolt passes'throughan open-j 'ing 15 in the end of the finger 8; is attached thereto by the nut 16.

From the pulley 13 attached vto one end of the foot lever 18. y

the cable 11 eXtendsA ythrough a slot 17 in the foot boardB andis block 12 and over the y ger`8.'" That is, the block 12 has' attached thereto one end of thestudl 95 The lever v18 has at its forward endthe i i lugs 19 thatare spaced apartA a'suficient distance to permit the insertion.k of the cable 11 Vwhich cable has its end looped about the bolt 20 which bolt when tightened grips the cable between the lugs 19.

The center portion of the lever 18 has therein thebearing 21 for the cotter pin 22; which cotter pin also passes through the upward extending lugs 23 of the bracket 24.

The bracket 24; has its base secured to the Jfoot board 3 by the screws 25; so that it is easily attached or detached.

There isadjustably mounted on the cable 11 a lug 26 which lug `has therein the set screw 27 by whichscrew the lug is secured to the cable in any predetermined place; and as seen in Fig. 2 this lug is secured to the cable 11 so that the lug contacts with the pulley 13 when the throttle valve 6 is closed;

' and the lug is held in contacting engage- Ytle valve will be closed and the lug 26fcontacting with the pulley 13.

kWith the parts in this position and the foot lever actuated the linger 8 will remain stationary holding the pulley block 12. in a fixed position while the cable llfmoves over the pulley 13 to move the lever 7 and open the throttle valve. In other words when foot pressure is applied tothe rear end 31 of the footflever 18 and it is moved from the full to the dotted line Vposition shown in Fig. 6 the cable 11 will be moved in the vdivrection of the arrow 2 shown in Figs. 2 and all, which movement of the cable will moveV the throttle valve 7 against the tension ot the spring 28 which movement will open the throttle. l

Or Yif desired the lever 10 can be actuated by the hand to move the linger 8 from f the full to the dotted line position shown in Fig. 2 whichV movement will also move the lever 7V to open the throttle valve; and as the movement of the throttle lever the throttle valve is against the tension of vthe spring 28 it-is obvious that the spring will close the throttle valve when the finger 8 is moved in the reverse direction. f

4F rom the foregoing it can readily be seen that the throttle valve is under'control and easily operated by eitherV thehand or foot;

also it is obvious that the throttle valve can be partlyl opened by the'hand lever for running the' engine atv medium or low speed and accelerated bythe footlever for highl speed.

Thatispif the hand lever 10 is actuated to move `the linger 8 fromY the full line posi- .ition shown in, Fig. 4l to the line A-A or about forty five degrees the throttle valve Vtion by means of the sector plate 30; and Vthat the foot lever can be used to cooperate T to open 'foot leve With this arrangement and combination of parts the change of engine speedl can be more quickly and easily accomplished than by moving the, throttle by hand; the adf vantages of which will be obvious to those accustomed to driving cars in crowded cities where traliic regulation requires that` drivers of vehicles start quickly on signal.y

It is also quite obvious that the lever 10 can be actuated to open the throttle valve.

any desired degree and held in that posiwith the hand lever-in any of the changed positions. q v

Also attention is called'to `the simplicity of the apparatus in construction, installation and operation.

The flexible connection or cable between.

the throttle lever 7 and the foot lever 18 may be of any suitable flexible material that will move over the I claim. v Y

1. In a hand and Vfoot accelerator, a throttle lever, a cable one endet which is 'attached to said throttle lever, a foot lever for moving said cable to actuateA the throttle lever, and the other end of said cable being attached to said foot lever, a lug mounted on said cable, a handv lever, and means Yon said hand lever to engage said lug to actuate the throttle lever. f

2. In a hand and foot accelerator, ath'rot tley lever, a flexible connection having A one end attached to said throttle lever, a foot lever for moving said flexibleY connection to actuate the throttle lever, the otherend of periphery of the pulley 13;

saidtleXible connection being attached to Y said foot lever, a hand lever, land means adjustably mounted on'v said llexible connection and adapted to'be engaged by said hand lever whereby said flexible connection can be ymoved independently ofthe foot lever.

3. In a hand and foot accelerator,a` throte .tle lever, a cable having one end attached to said throttle lever, ay foot lever to which is attachedV the other endy of said cable, a lug on said cable, aV handlever adapted toV move a pulley, andv means wherebythe pul-r ley moved by the hand leverl will engagesaid cable, a pulley engaging said cable and normally contacting With said lng, whereby operation ofthe foot lever can move said cable to open the throttle valve Without moving said pulley, a hand lever for moving said pulley to open the throttle valve, and a spring for returning the throttle valve to a closed position.
